Description 18-22
Agricultural production depends on environmental factors such as climate, soil fertility and other several crop improvement
measures like fertilizers, manures, improved crop varieties, irrigation, cropping pattern, plant protection measures and cultural
practices etc. Crop productivity can be maximized by improving plant nutrients and soil fertility. Often soil conditions do not
support optimum growth due to lack of or low doses of specific nutrients. Sixteen plant food nutrients are essential for proper
crop development. For this purpose, an experiment on monitoring of macro- and micro- nutrients with recommended dose of
NPK in rice-wheat cropping system under semi-arid eco-system was conducted during the period 1997-98 to 2000-01 at CSR
centre Kanpur. The results of the combined analysis of these experiments revealed that the grain and straw yields and gross
returns increased due to the application of all levels of sulphur, zinc chloride or zinc oxide and zinc sulphate. Total gross
returns of grain yields for both the crops in kharif and rabi seasons were found significant when higher dose of zinc at 10 kg/
ha as basal in the form of zinc sulphate with recommended dose of NPK applied. It was 26% higher than control. The
micronutrients were applied every year in kharif season gave higher yields of both grain and straw and also gross return of
yields for both seasons than micronutrients applied alternate year in kharif season.
